The SOLECTRIA PVI 25TL-208, PVI 50TL-480, and PVI 60TL-480 3-phase inverters must be installed in accordance
with the National Electric Code, NFPA 70, and any State Codes or local jurisdictions. An online based Solar PV
string sizing tool is available https://solectria.com/support/string-sizing-tool/. This is an optional design tool to
help guide designers by matching the PV panel type and quantity to the inverter's power rating.
Prior to performing any electrical installation, ensure the M6x18 screws (4pcs) installed in Section 3.2.5.5 for
mounting the Inverter onto the Bracket are properly torqued and the area under the bolt-head is clear of paint.
This connection provides an electrical ground bond of the wiring box to the upper/main enclosure.
